M7 x 20 tapered socket head

[ncskibum]

Hi,

One of the bolts fell out of my head ;-) and I can't find a
replacement, either at local bike shops or online. I did find the
same size bolt at Ace Hardware with a hex head and am using that
temporarily. The size is a M7 x 20, tapered socket head. A 5mm allen
fits it.

Anyone know where to find this? Here's a picture from a UK website
that sells them http://www.tastynuts.com/acatalog/TISC720.jpg
(I don't want to order it from that place b/c it would cost me $26 for
1 bolt!)

Thanks, Carol
